As I began working on a new feature for our project, I followed the developer guide’s suggestion to ensure consistent line endings by adding * text eol=lf to the .gitattributes file. This seemed straightforward enough, but as I proceeded, I encountered some unexpected behavior that left me puzzled.
After creating a new branch and committing the change to .gitattributes, I made some modifications to a Java file. Running git status showed that the file had been modified, which was expected. However, when I ran mvn spotless:apply, it cleaned up a significant number of files across the project. This included not just the files I had modified but also many others, which I hadn’t anticipated.
The sheer number of files reported as modified after running spotless:apply was overwhelming. I couldn’t help but wonder if I had misunderstood the purpose of the .gitattributes change or if the instructions were no longer applicable. I recalled seeing a discussion about Git configurations for line endings, but I wasn’t sure if that was the right path to explore.
I decided to look into the Git configuration settings mentioned in the discussion, specifically git config --global core.autocrlf false and git config --global core.eol crlf. While this seemed like a logical step, I was still unclear why core.eol wasn’t set to lf by default, as that seemed more intuitive to me.
My goal is to contribute a PR, so understanding how to manage these settings correctly is crucial. I want to ensure that my changes don’t introduce unnecessary conflicts or issues for others working on the project. If anyone has insights or best practices for handling line endings and file cleanups in Git, especially in the context of Maven projects, I’d greatly appreciate the guidance!
This experience has highlighted the importance of thoroughly understanding Git configurations and how tools like spotless interact with them. I’m eager to learn more to avoid similar confusion in the future and to contribute effectively to the project.
